Most of us are the only child in our family. We have no brothers or sisters. Our family mainly consists of our mom,our dad and us. We are growing up in a world differently from our parents’. And we will be the future leaders of China. Some day we have to work hand in hand with each other and make China more and more beautiful. So we must learn to love each other like brothers and sisters.
It’s hard to think how difficult life would be if we had a sibling(同胞，手足).We never have to share anything at home. Of course, we might have cousins, but we don’t have to live with them! Our parents try to give us the best, and the best doesn’t need sharing between two or three children. Do we ever ask ourselves if we are (宠坏) spoiled?
A recent study has found that many children don’t know how to love others! We don’r know the value of money. We don’t know how hard our parents are to support us. We don’t want others to regard us as spoiled, do we? Well, why not start now to help our parents at home, share a game with one of our friends or value the opinions of our classmates, even if we don’t always agree? In a word, we must learn to love each other!
【小题1】The underlined phrase “consists of ” means ____________in Chinese.

The Mississippi

       The Mississippi is a great river whose relationship with man goes way back beyond its discovery in the 16th century. The River Indians used it as a highway and as a source of food, and it was they who gave it its name—“misi” meaning “great” and “sipi” meaning “water”．When the length of its branch, the Missouri, is added to it, the Mississippi becomes greater.  From the source of the Missouri to the tip of the delta (三角洲), it is 2, 480 miles long.

       Great rivers are likely to suffer floods. In 1927 the Mississippi flooded 26 thousand acres, sweeping away farms, towns, everything in its path. In 1938 its floods drowned or killed 200 people and made millions homeless. Today the river has largely been controlled.   .

       Industries have spread down some of the waterways of the delta, but otherwise the delta is a remote place, the homeland of a little colony of French Canadians that the British drove out of Nova Scotia in the 18th century. They still speak French, mixed with English, Indian, Spanish and Negro idioms. They keep to themselves, farming the rich soil of the delta.  .

       Pioneers who first reached its banks wondered not only where it went, but what lay beyond. In 1764 the French founded a city on the right bank of the river, and named it after their king, Louis XV. This city, named St. Louis, became the jumping-off(起点) place for the adventurous men and women who opened up the Great Plains, and the way to the Far West.

       Some 40 years earlier, at the beginning of the 18th century, the French had founded another city just above the Mississippi delta, New Orleans.  . New Orleans is one of the great ports of the world, and one of the greatest terminals for both sea and river traffic.

       A．It was the Mississippi that made the city what it is

       B．Levees, high banks built of earth, hold back the flood waters

       C．Therefore, as we know, it’s the third longest river in the world

       D．It is known that the “Great Water” has also been a frontier river

       E．However, they paddled up and down the Mississippi in their boats to seek their fortune

       F．The “Great Water” always remains a threat, for the streets of the city are below the level

of the river

       G． They call themselves Cajuns, who have actually been leading fairly primitive lives and

preserving their own traditions

A chemical important of brain development may play a role in explaining why some people are genetically (由基因决定地) likely to suffer from anxiety and could lead to new treatments, U．S. researchers said.

They said highly anxious rats which were kept had very low levels of a brain chemical called fibroblast growth factor 2 or FGF2, compared with rats that were more relaxed. But when they improved the anxious rats' living conditions—giving them new toys to explore and a bigger cage to live in—levels of this brain chemical increased and they became less anxious.

“The levels of this brain chemical increased in response to the experiences that the rats were exposed to. It also decreased their anxiety.”Javier Perez of the University o f Michigan said in a telephone interview. “It made them behave the same way as the rats that were relaxed，”he said.

In a former study of people who were severely depressed before they died, the team found the gene that makes FGF2 was producing very low levels of the growth factor, which is known primarily for organizing the brain during development and repairing it after injury.

Perez thinks the brain chemical may be a marker for genetic vulnerability (脆弱性) to anxiety and depression. But it can also respond to changes in the environment in a positive way, possibly by preserving new brain cells.

While both the calm and anxious rats produced the same number of new brain cells, these cells were less likely to survive in the high－anxiety rats, the team found. Giving the rats better living conditions or injecting them with FGF2 helped improve cell survival.

“This discovery may pave the way for new, more specific treatments for anxiety that will not be based on sedation(药物镇静), but will instead fight the real cause of the disease，” Dr. Pier Vincenzo Piazza from France said in a statement.

6. We know from the passage that with the levels of FGF2 decreasing, the rats will ________.

A. die of anxiety soon          B. suffer from a headache

C. become more relaxed        D. become more anxious

7. What's the better way to increase the levels of FGF2?

A. Introducing more companions to the anxious rats.

B. Improving the living conditions of the anxious rats.

C. Injecting the anxious rats with some special medicine.

D. Giving the anxious rats more time to relax.

8. The underlined word “it” in Paragraph 4 refers to ________.

A. the team                 B. the gene

C. the growth factor          D. the brain

9. What's the main influence of the new discovery?

A. Doctors won't use any medicine to cure anxiety.

B. Doctors may treat anxiety more efficiently.

C. Doctors will find the real cause of anxiety.

D. Doctors may find new medicine for anxiety.

10. Which of the following would be the most suitable title for the passage?

A. Anxious rats and relaxed rats

B. Anxiety—a serious mental disease

C. Scientific research into the brain is important

D. Brain chemical may play key role in anxiety
